Detailed environmental destruction case study of the Zhonghua Group (ChemChina)

The Zhonghua Group (ChemChina), a state-owned enterprise of the Chinese government, is one of the largest chemical companies in the world, manufacturing pesticides, chemical products, plastics, and other products. While the company has a broad influence especially in the production of pesticides and chemical fertilizers, it has also reported many cases of environmental destruction in the past. The following is a detailed description of some of the major cases of environmental destruction by the Zhong Hua Group, including place names, substances, and specific figures.

Water Pollution in Hebei and Hunan Provinces
Zhonghua Group's chemical plants are located in Hebei and Hunan provinces, and wastewater from these plants causes water pollution in the surrounding areas. In particular, hazardous wastes generated in the process of pesticide production are released into rivers and groundwater with inadequate treatment, causing serious impacts on residents. Specifically, large amounts of heavy metals such as cadmium and lead have been detected, and lead concentrations of up to 1.2 mg/L have been observed at some locations as a result of the discharge into rivers. More than 2,000 residents complained of health problems as a result of this contamination, with particular effects on the kidneys and liver being reported.

Air Pollution in Beijing
The factory of the Zhong Hua Group in Beijing emitted large amounts of volatile organic compounds (VOCs) and sulfur dioxide (SO2) into the air during the production of pesticides and chemical products; according to a 2019 report, annual emissions of sulfur dioxide from the factory amounted to approximately 200,000 tons, which contributed significantly to the increase in PM2.5 concentrations in Beijing. In particular, smog has become more severe during the winter months, with PM2.5 concentrations exceeding 200 µg/m³ on some days. This has had a serious impact on the health of residents, with reported increases in respiratory and heart diseases.

3. pollution due to pesticide abuse in Hebei and Shandong provinces
The Zhonghua Group is a major producer of pesticides, especially organophosphorous and neonicotinoid pesticides, and environmental pollution due to excessive use of pesticides is ongoing. In Hebei and Shandong provinces, pesticides such as chlorpyrifos and imidacloprid are used extensively, and their infiltration into groundwater has become a problem. As a result, chlorpyrifos concentrations in groundwater have reached 0.8 mg/L, which is more than twice the safety standard set by the Chinese government. These pesticides have also caused mass deaths of honeybees and have had a serious impact on the agricultural ecosystem.

4. global impact of the Syngenta acquisition
In 2017, the Zhonghua Group acquired Swiss agrochemical and seed company Syngenta, thus becoming the world's largest agrochemical and seed company. Syngenta promotes the development and marketing of neonicotinoid pesticides and genetically modified crops, and the environmental impact of its activities is a global concern. In particular, Syngenta's pesticides have been used extensively in the Amazon region of Brazil, where soil erosion and water pollution have been reported. A survey by a Brazilian environmental group confirmed that clothianidin concentrations reached 1.5 mg/L in water bodies after the pesticide was used, with serious effects on the ecosystem and local residents.

general summary
Due to its size and influence, the Zhonghua Group (ChemChina) is causing serious environmental problems in China and abroad. In particular, water pollution, air pollution, and the destruction of ecosystems due to excessive use of pesticides are prominent, and the specific figures and the damage caused by the company's activities are extensive. With increasing pressure from governments and the international community to address these issues, there is a need for sustainable operating methods and environmental protection initiatives.
